housing for radiation detector

ABSTRACT

A METALLIC PROTECTIVE HOUSING FOR A RADIATION DETECTOR OR THE LIKE THAT INCLUDES A SCINTILLATION CRYSTAL FOR RECEIVING SHORT WAVE LENGTH RADIATION, SUCH AS GAMMA RADIATION, AND CONVERTING IT TO A LONGER-WAVE-LENGTH, VISIBLE LIGHT IMAGE, A PHOTOMULTIPLIER TUBE 10 FOR CONVERTING THE VISIBLE LIGHT IMAGE TO AN ELECTRICAL SIGNAL, AND AN OPTICAL WINDOW 12 INTERPOSED BETWEEN THE SCINTILLATION CRYSTAL 11 AND THE PHOTOMULTIPLIER TUBE. THE HOUSING 13 SUPPORTS THE ABOVE COMPONENTS IN ASSEMBLED, OPTICALLY ALIGNED RELATION AND HAS A LAYER OF IMPERVIOUS CHROME PLATING 35 DEPOSITED THEREON TO PROVIDE A SURFACE THAT MAY BE EASILY CLEANED OF ANY HARMFUL RADIOACTIVE MATERIAL. THE ACCOMPANYING DRAWING FIGURE IS AN EXPLODED FRAGMENTARY SECTIONAL VIEW ILLUSTRATING THE ABOVE LISTED COMPONENTS OF THE HOUSING AND THEIR MANNER OF ASSEMBLY.
